What is the manufacturing background and key details of Q235 straight seam welded steel pipe
Q235 welded steel pipe is a steel pipe made from Q235 steel strip or plate through rolling and welding. Because its production process uses high-frequency welding technology, it is also called high-frequency welded pipe. As a representative product of carbon structural steel welded pipes, Q235 we...Read more -
What are the causes and adjustment measures for uneven wall thickness in steel pipes
1. The causes of spiral-shaped uneven wall thickness in steel pipes are: uneven wall thickness caused by misalignment of the piercing mill rolling centerline, unequal inclination angles of the two rolls, or insufficient pre-pressurization of the mandrel. This unevenness generally presents a spira...Read more -
